The drum spin-rotates very fast and the clothes are forced to the drum walls due to centrifugal force. (things being spun tend to head to the edges), The wall of the drum, in the washer, has many holes that allow water particles to pass through the wall to be dumped. The spinning squeezes the clothing against the wall and presses much of the water out of the clothes and out of the drum.
European washers have motors that reach ultracentifugal revolutionary speeds that drive out almost all of the water from the laundered clothes thus making drying & dryers unecessary.

A "centrifugal force" would be a force that acts directly away from the center. There are some details, but basically there is no such thing as centrifugal force. What most people think of as centrifugal force is really an artifact of inertia. A "centripetal force" is a force that acts towards the center. Any object which is moving in something other than a straight line - anything which is curving, in other words - is experiencing a centripetal force. If you put a stone on a string and swing it around your head, the string is exerting a centripetal force on the stone. The Moon is orbiting the Earth - the Earth's gravitational field is exerting a centripetal force on the Moon. A car is going around a turn - friction from the road is exerting a centripetal force on the tires of the car.

wow at the "theres no such thing as centrifugal force" comment.
The centrifugal force is caused by the rotation of the drum. The faster the rotation, the higher the force radially expelling the fluid from the clothes/materials. I agree with the bucket of water analogy. If you fill a bucket of water and spin it round the water would stay in the bucket. If you had a hole in the bucket, the fluid would leave the hole. If the rotation was increased the force of the fluid leaving the hole would increase.

Centrifugal force is used to extract the water from the clothes. The timer causes the transmission to go to high speed rotary motion, which causes the basket to spin rapidly. Centrifugal force pushes the clothes against the side of the basket and forces out the water. Meanwhile, a pump is ejecting the waste water into the drain line.

No such thing as centrifugal force... The velocity of the clothes in the bin causes the clothes to collide with the wall when the bin starts spinning. The walls of the washing machine push the clothes toward the axis of the machine. Since it is difficult to push a liquid and the bin has holes in it, the water "falls" through the bin, leaving only damp clothes. There is no force pushing the clothes to the outside, just as there is no force pushing up the International Space Station as it orbits the Earth. It's all about speed and centripetal force.

Since when do we say there is no such thing as centrifugal force?? Thats just absurd, I'm a mechanical engineering student and that would mean they've been teaching me crap the past 3 years? I don't buy that..

Its simple, much like when you spin a bucket of water, the water stays in the bucket, only the washing machine concept is reversed. When the washing machine spins the water is pulled out towards the edge of the basin. Holes in the basin drain out the water
